You're afraid you'll kill your wife, or your wife will kill you?
I've used them several times, both the carts that have a mini mixer and the ones that are just a big dump bed. Good results in each circumstance. The quality of concrete from the mini mixer was probably better, but the dump trailers were easier to pour from and control delivery. My situation was I had a bit of concrete to pour on the back of my lot and didn't want to back a truck up or pay for a pump.
I saw that there was an additional charge for the mixing type, why is the dump easier? I assumed they both tilted.... I did the dump thing before with another company and it was quite imitating driving home with a bucket of crete behind me... The mixer seemed to be the way to go...
It would be a huge help if your wife could return the cart back to them, while you stayed to work the mud. I had to return it a couple times, and that stuff drys a lot quicker when you aren't there waiting on it.
I did it 2 1/2 yards at a time
You need to call me!!! Ya know what I mean?
Good call on that one BC, I'll have the wife drive it back. I figure I need 6.5+ yards. On the third load (these will come some weeks apart) I will start in another area of the yard to finish off the 2 1/2, just another 16x50' area....
Did you use the bucket or the mixer?
Give me a holler when you get ready to do the big pour, maybe I can come give you a hand.
Oh, and I've got about 1/2 of a roll of Re-mesh left over, if you want to come grab it.
